Bit 7: Performance Monitoring Update Mode (PMUM) – When 0, a performance monitoring update is initiated by
the LPMU register bit. When 1, a performance monitoring update is initiated by the global or port PMU register bit.
Note: If the LPMU bit or the global or port PMU bit is one, changing the state of this bit may cause a performance
monitoring update to occur.
Bit 6: Local Performance Monitoring Update (LPMU) – This bit causes a performance monitoring update to be
initiated if local performance monitoring update is enabled (PMUM = 0). A 0 to 1 transition causes the performance
monitoring registers to be updated with the latest data, and the counters reset (0 or 1). For a second performance
monitoring update to be initiated, this bit must be set to 0, and back to 1. If LPMU goes low before the PMS bit
goes high; an update might not be performed. This bit has no affect when PMUM=1.
Bit 5: Receive New Pattern Load (RNPL) – A zero to one transition of this bit will cause the programmed test
pattern (QRSS, PTS, PLF[4:0}, PTF[4:0], and BSP[31:0]) to be loaded in to the receive pattern generator. This bit
must be changed to zero and back to one for another pattern to be loaded. Loading a new pattern will forces the
receive pattern generator out of the “Sync” state which causes a resynchronization to be initiated. Note: QRSS,
PTS, PLF[4:0}, PTF[4:0], and BSP[31:0] must not change from the time this bit transitions from 0 to 1 until four
receive clock cycles after this bit transitions from 0 to 1. Register bit PORT.CR1.BENA must be set and the receive
clock running in order for the pattern load to take affect.
Bit 4: Receive Pattern Inversion Control (RPIC) – When 0, the receive incoming data stream is not altered.
When 1, the receive incoming data stream is inverted.
Bit 3: Manual Pattern Resynchronization (MPR) – A zero to one transition of this bit will cause the receive
pattern generator to resynchronize to the incoming pattern. This bit must be changed to zero and back to one for
another resynchronization to be initiated. Note: A manual resynchronization forces the receive pattern generator
out of the “Sync” state.
Bit 2: Automatic Pattern Resynchronization Disable (APRD) – When 0, the receive pattern generator will
automatically resynchronize to the incoming pattern if six or more times during the current 64-bit window the
incoming data stream bit and the receive pattern generator output bit did not match. When 1, the receive pattern
generator will not automatically resynchronize to the incoming pattern.
Bit 1: Transmit New Pattern Load (TNPL) – A zero to one transition of this bit will cause the programmed test
pattern (QRSS, PTS, PLF[4:0}, PTF[4:0], and BSP[31:0]) to be loaded in to the transmit pattern generator. This bit
must be changed to zero and back to one for another pattern to be loaded. Note: QRSS, PTS, PLF[4:0}, PTF[4:0],
and BSP[31:0] must not change from the time this bit transitions from 0 to 1 until four transmit clock cycles after this
bit transitions from 0 to 1. Register bit PORT.CR1.BENA must be set and the receive clock running in order for the
pattern load to take affect.
Bit 0: Transmit Pattern Inversion Control (TPIC) – When 0, the transmit outgoing data stream is not altered.
When 1, the transmit outgoing data stream is inverted.
